Frame rate drops when mods are installed?

Since the recent re-uploading of Open IV I've gone absolutely nuts when modding yet again, I have noticed however that I get frequent Frame drops when driving around the world, normally this wouldn't happen, I was just wondering if there was anything that can be done? Thanks for your time.

try to activate shader cache in the nvidia settings and also turn off v sync.
I had the same issue and simply limited my framerate to 50 in the nvidia control inspector this got rid of my stuttering maybe it helps you too + don't forget to lower your grass/foliage setttings to high.

@Cyplays Never understood people's obsession with FPS. The ONLY time I am ever forced to even think about it, is if the FPS dips to an unplayable state (under 20 FPS). This has never happened to me, so I don't GAF what my actual FPS is. If your FPS dips to an unplayable state, I would run a couple benchmarks both modded and unmodded. From there, it is just a matter of isolating the offending mod/script/s.

@eshenk See my obsession isn't with frames at all, I know I get enough frames for it to be enjoyable 90% of the time, it's just that 10% that ruins it, because I like to do machinima, and while recording the frame drops ruin my videos.
